EMI suppression support service (Free of charge)

We conduct verification of conductive noise (terminal noise) to select the optimum coil to meet your needs.


-
Compared to the conventional method of proposal made based on customers’ specifications and requests, this saves the trouble of reviewing.
And we can also conduct witnessed inspections. -
The best coil can be obtained through selection from among our wide variety of products or customization.
-
As noise evaluation and coil selection are conducted simultaneously, the development time can be shortened.
